Single-center experience of organ transplant practice during the COVID-19 epidemic.

ABSTRACT: In order to safely carry out organ donation transplants during the outbreak of coronavirus disease 2019 (COVID-19), we have formulated strict procedures in place for organ donation and transplantation. We retrospectively analyzed our transplantation work from January 20 to May 5, 2020, to discuss whether organ transplantation can be carried out safely during the epidemic period. From January 20 to May 5, 43 cases of donation were carried out in our hospital, and the utilization rate of liver, kidney, heart, lung, and pancreas donations was more than 90%. Forty-one cases of liver transplantation and 84 cases of kidney transplantation were performed. No graft loss or recipient death occurred within one month after kidney transplantation, and one patient (2.4%) died after liver transplantation. There was no significant difference in the length of hospital stay compared with that during the same period in the previous three years. More importantly, COVID-19 infection did not occur among healthcare providers, donors, patients, or their accompanying families in our center. Under the premise of correct protection, it is safe and feasible to carry out organ transplantation during the epidemic period. Our experience during the outbreak might provide a clinical reference for countries facing COVID-19 worldwide.

Project description:BackgroundSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is commonly associated with myocardial injury and heart failure. The pathophysiology behind this phenomenon remains unclear, with many diverse and multifaceted hypotheses. To contribute to this understanding, we describe the underlying cardiac findings in fifty patients who died with coronavirus disease 2019 (COVID-19).MethodsIncluded were autopsies performed on patients with a positive SARS-CoV-2 reverse-transcriptase-polymerase-chain reaction test from the index hospitalization. In the case of out-of-hospital death, patients were included if post-mortem testing was positive. Complete autopsies were performed according to a COVID-19 safety protocol, and all patients underwent both macroscopic and microscopic examination. If available, laboratory findings and echocardiograms were reported.ResultsThe median age of the decedents was 63.5 years. The most common comorbidities included hypertension (90.0%), diabetes (56.0%) and obesity (50.0%). Lymphocytic inflammatory infiltrates in the heart were present in eight (16.0%) patients, with focal myocarditis present in two (4.0%) patients. Acute myocardial ischemia was observed in eight (16.0%) patients. The most common findings were myocardial fibrosis (80.0%), hypertrophy (72.0%), and microthrombi (66.0%). The most common causes of death were COVID-19 pneumonia in 18 (36.0%), COVID-19 pneumonia with bacterial superinfection in 12 (24.0%), and COVID-19 pneumonia with pulmonary embolism in 10 (20.0%) patients.ConclusionsCardiovascular comorbidities were prevalent, and pathologic changes associated with hypertensive and atherosclerotic cardiovascular disease were the most common findings. Despite markedly elevated inflammatory markers and cardiac enzymes, few patients exhibited inflammatory infiltrates or necrosis within cardiac myocytes. A unifying pathophysiologic mechanism behind myocardial injury in COVID-19 remains elusive, and additional autopsy studies are needed.
